JOHN c. ircLAUGHLiN,

OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO UNEBWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y., A. CORPORATION JERSEY.

TYPE-WRITING MACHINE.

Be it known that I, JOHN C. MGLAUG'H- LIN, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in ATypelfVriting'Machines, of which the following is a specification.

This invention relates to tabulating mechanisms of typewriting and other machines, and is in the nature of an improvement on the devices disclosed in United States Patent N o. 820,505. vIn said patent is shown a row of column stops, and a rotatable shaft orbar extending along the row, and having projections formedthereon to select or act upon diierent sets of column stops and move some of the latter to idle positions.

The objects of the present invention are to enable the column stops to be disposed at letter space intervals where desired, to improve and simplify the construction and operation of the column selectors directly upon the selector bar, and also to make it practicable to set up` a machine `:for any desired variety of tabulating work, by the use of previously manufactured parts.

In carrying out the present invention, the column stops are formed upon sliding plates, the latter mounted in racks to permit the column stops to slide intoand out of working positions. The plates ,are adjustable to any 'desired positions along the racks.

In place of forming the selectors or cams directly upon the rotative selector bar, by cutting notches in said bar, as in said patent, I employ a plain bar or shaft upon which I set the desired selectors at the desired points. cylindrical and the'selectors are in the forms of collars placed upon the bar and having diversified cams, adapted to engage lugs upon the column stop plates to set different sets of column stops to working positions, according to the point to which the selector shaft is rotated. The cam collars may be adjusted along the shaft to correspond with Specication of Letters Patent. Application led May 26, 1908. Serial No. 435,161.

steps and selectors, and to avoid the necessity of' formingfthe The bar or shaft is preferably the adjustment of the column' stop plates, and hence the machine may be, setv up 'for any desired variety of tabulating work, and may readily be readjusted as required.

Other features and advantages will hereinafter appear.

A paper carriage 1 is propelled by a spring barrel 2 through a strap 3, and has an escapement rack 4 to mesh with a pinion 5 connected with an escapeinent wheel 6. Upon depression of yany one of a series of denomination keys 7 its lever 8 is vibrated, and its rod 9 thrust up to cause a denomination stop 10 at its upper end to rise into the path of a column stop 11 formed on the forward end of a slidable plate 12 mounted.

upon the carriage. Each rod 9 has a jog 13 to operate a universal bar 14 fulcrumed at 15 and having an arm 16 to thrust up a link 17, the latter connected to a lever 18 having a roll 19 to lift the rack 20 out of mesh with the escapement pinion 5, so that the carriage is drawn along bylthe spring barrel 2 and strap 3 until arrested by engagement of the column stop 1'1 with the elevated denomination stop 10.

jThe main or forward column-stop rack'21 is--supported i rearwardly from the ends of the carriage. A rear rack 23 is detachably supported at its ends upon arms 24 by means of screws V25; said arms rigidly secured at their forward ends upon the ends of the rack bar 21, being preferably perforated as at 26 to receive the endsof said bar and also having ears 2T underlyingsaid ends and attached thereto by screws 2S.

Each column'stop plate 12 isforlredat its ,forward end as at 29 to slide in notches 30. 31 formed on the topand bottom respectively of .the rack bar 21. It is also forked at its rear end at 32 to fit onto the rear rack bar 23, the latter being in the form of a' channel bar'having notches 33 in its 11p-- is supported' by its ends upon said-racks,ex
